Description

Technical Field

[0001] The invention relates to the technical field of laser welding tooling, in particular to a laser welding device for a long baffle of a radiator. Background Art

[0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. Laser welding is mainly used for welding thin-walled materials and low-speed welding. The welding process is a heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts.

[0003] At present, in order to ensure the accuracy of welding when welding the long baffle of the radiator, it is usually necessary to design corresponding tooling to fix the workpiece and the long baffle. Now, when welding the long baffle of the radiator, the workpiece and the long baffle need to be placed manually. In the absence of guidance, the operator may misplace the workpiece. When the long baffle of the radiator is welded by laser, metal slag will be generated at the same time. These debris will gradually accumulate inside the tooling as the number of welding increases, thereby affecting the accuracy of the workpiece fixing position, and then affecting the welding quality.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0041] When welding the long baffle of the radiator, the placement block 302 and the positioning protrusion 307 set on the placement block 302 can facilitate the operator to quickly place the workpiece and the long baffle, and the positioning protrusion 307 can effectively prevent the wrong placement of the workpiece. After completing the initial assembly of the workpiece and the long baffle in the placement groove 305, the clamping cylinder 303 can drive the contact plate 306 to clamp and fix the workpiece in the placement groove 305 to ensure the stability of the workpiece during welding. At the same time, the rotating clamping cylinders 304 located at both ends of the tooling base plate 301 can press and fix the long baffle on the workpiece, further improving the stability of the workpiece during welding, until the welding is completed by the welding robot 2 on the other side of the conveyor table 1, effectively improving the welding efficiency.

[0042] Specifically, Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 As shown, the driving structure 4 includes a mounting plate 401, the bottom side of the tooling bottom plate 301 is fixedly connected with the mounting plate 401, the mounting plate 401 is slidably connected to the conveying platform 1, a motor 402 is installed at the end of the conveying platform 1, the end of the motor 402 is fixedly connected with a screw rod 403 through a coupling, the screw rod 403 is rotatably connected to the conveying platform 1, and the mounting plate 401 and the screw rod 403 are threadedly connected;

[0043] After the motor 402 at the end of the conveying platform 1 is electrically connected to an external power source, the driving effect of the motor 402 can drive the mounting plate 401 and the tooling on the mounting plate 401 to move as a whole, so as to facilitate welding.

[0044] Specifically, Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Fig.10 , Fig.11 , Fig.12 , Fig.13 As shown, the cleaning structure 5 includes a guide plate 502, the placement block 302 is provided with a guide plate 502 in the placement groove 305, the guide plate 502 is rotatably connected to the placement block 302, a first torsion spring 504 is fixedly connected between the guide plate 502 and the placement block 302, the guide plate 502 is obliquely arranged, a drop groove 508 is opened on the tooling bottom plate 301, a side rack 501 is fixedly connected to the side of the conveying platform 1, and the mounting plate A lifting rod 505 is slidably connected to the inner side of 401, and the lifting rod 505 penetrates the tooling bottom plate 301. The end of the guide plate 502 is fixedly connected to the abutting inclined plate 503, and the end of the lifting rod 505 abuts against the bottom side of the abutting inclined plate 503. The bottom end of the lifting rod 505 is fixedly connected to a tooth block 506, and a first spring 507 is fixedly connected between the tooth block 506 and the mounting plate 401, and the tooth block 506 is meshed with the side rack 501;

[0045] An inclined guide plate 502 is provided at the bottom side of the placement block 302. When the motor 402 drives the mounting plate 401 and the tooling arranged on the mounting plate 401 to move through the screw rod 403, the tooth block 506 arranged on the bottom side of the mounting plate 401 will be in a meshing state with the side rack 501 on the side of the conveyor platform 1. At the same time, since the mounting plate 401 is in a moving state, the tooth block 506 will oscillate longitudinally under the push of the first spring 507, and then the resisting inclined plate 503 at the end of the guide plate 502 is repeatedly pushed by the lifting rod 505, and finally the guide plate 502 is oscillated when the mounting plate 401 moves. In this way, the waste chips generated during the welding process will eventually be discharged into the drop groove 508 on the tooling bottom plate 301, so as to avoid the accumulation of debris on the bottom side of the placement block 302 and affect the placement of the workpiece.

[0046] Specifically, Figure 6 , Figure 7 , Figure 8 , Fig.10 , Fig.12 , Fig.13As shown, the collecting structure 8 includes a first roller 802 and a second roller 804, the inner side of the mounting plate 401 is rotatably connected with the first roller 802 and the second roller 804, a conveyor belt 803 is sleeved between the first roller 802 and the second roller 804, the conveyor belt 803 is arranged on the bottom side of the drop groove 508 opened on the tooling bottom plate 301, a collecting box 801 is arranged on the bottom side of one end of the conveyor belt 803, the collecting box 801 is slidably connected to the mounting plate 401, the end of the second roller 804 is fixedly connected with a first gear 805, the side of the first gear 805 is meshed with a second gear 806, the second gear 806 is rotatably connected to the mounting plate 401, and the second gear A first bevel gear 807 is fixedly connected to the side of 806, a second bevel gear 808 is meshed with the side of the first bevel gear 807, a third gear 809 is fixedly connected to the side of the second bevel gear 808, the third gear 809 is rotatably connected to the mounting plate 401, the side of the third gear 809 is meshed with the side rack 501, a positioning groove 812 is provided on the side of the collection box 801, a positioning rod 810 is slidably connected to the inner side of the mounting plate 401, the end of the positioning rod 810 is a hemispherical structure, a fourth spring 811 is fixedly connected between the positioning rod 810 and the mounting plate 401, and the spherical end of the positioning rod 810 conflicts with the collection box 801 through the positioning groove 812;

[0047] When the metal scraps fall into the drop groove 508 of the tooling bottom plate 301, a conveyor belt 803 sleeved on the first roller 802 and the second roller 804 is provided in the mounting plate 401 at the bottom of the drop groove 508. After the workpiece is welded, when the mounting plate 401 returns to its initial position, the third gear 809 located at the bottom side of the mounting plate 401 will be meshed with the side rack 501, and the third gear 809 will rotate accordingly. At this time, the second gear 806 is driven to rotate by the transmission effect of the first bevel gear 807 and the second bevel gear 808, and the first gear fixed at the end of the second roller 804 is rotated. 805 is meshed with the second gear 806, thereby ultimately driving the conveyor belt 803 to rotate through the rotation of the second roller 804, and as the guide plate 502 continues to oscillate, during the process of the mounting plate 401 returning to its position, the debris falls onto the conveyor belt 803 via the guide plate 502, and is transported to the position of the second roller 804 through the conveyor belt 803, and finally falls and is concentrated in the collection box 801 on the bottom side, facilitating subsequent centralized cleaning. At the same time, the side of the collection box 801 is fixed by a positioning rod 810 to prevent the collection box 801 from falling out during the movement of the mounting plate 401.

[0048] Specifically, Figure 1 , Figure 3 , Figure 7 , Fig. 9 , Fig.11 , Fig.14 , Fig.15 , Fig.16 As shown, the storage structure 6 includes a storage box 601, a storage box 601 is provided on the side of the conveying platform 1, a plurality of pulleys 603 are rotatably connected to the side of the storage box 601, two hook rods 605 are rotatably connected to the side of the storage box 601, a second torsion spring 606 is fixedly connected between the hook rod 605 and the storage box 601, a guide rod 604 is fixedly connected to the side of the conveying platform 1, the end of the hook rod 605 is engaged with the side of the guide rod 604, a traction plate 607 is provided on the side of the storage box 601, a limiting groove 608 is provided in the middle of the traction plate 607, and the traction plate 607 The traction plate 607 is slidably connected to the storage box 601 through the limiting groove 608, and a second spring 609 is fixedly connected between the traction plate 607 and the storage box 601. The storage box 601 is provided with a pull rod 602, and the two ends of the pull rod 602 are respectively rotatably connected to the two opposite sides of the storage box 601. One end of the traction plate 607 is provided with a first slide groove 610, and the end of the pull rod 602 is slidably connected to the traction plate 607 through the first slide groove 610. The other end of the traction plate 607 is provided with a second slide groove 611, and the traction plate 607 is slidably connected to the two hook rods 605 arranged on the same side through the second slide groove 611;

[0049] A storage box 601 for storing workpieces to be welded is provided on the side of the conveyor platform 1. A pulley 603 is provided on the bottom side of the storage box 601 for moving the box as a whole. In order to facilitate the transportation and retrieval of the workpieces, a hook rod 605 is provided on the side of the box. When the storage box 601 slides to the side of the conveyor platform 1, the hook rod 605 will automatically engage with the guide rod 604 on the side of the conveyor platform 1 under the action of thrust, so that the storage box 601 can be quickly fixed at any position on the side of the conveyor platform 1 as needed, which is convenient for the operator to take the workpiece through the storage box 601. When the box 601 is transporting the workpiece, the user only needs to press the pull rod 602 on the side to make the pull rod 602 rotate. At this time, the end of the pull rod 602 will slide in the first slide groove 610 at one end of the traction plate 607 and push the traction plate 607 to one side at the same time. After sliding between the traction plate 607 and the storage box 601, the end of the traction plate 607 will push the two hook rods 605 engaged with the guide rod 604 through the second slide groove 611 at the same time, so that the hook rod 605 rotates and releases the engagement state with the guide rod 604. At this time, the user can remove the storage box 601 for easy use.

[0050] Specifically, Figure 1 , Fig.16As shown, the access structure 7 includes a partition 701, the inner side of the storage box 601 is fixedly connected with the partition 701, and a plurality of slots 705 are provided on both sides of the partition 701. The storage box 601 is slidably connected with a supporting plate 702 on both sides of the partition 701, and a lifting rod 707 is rotatably connected to the side of the supporting plate 702. One end of the supporting plate 702 is slidably connected with a bevel tooth 703, and a third spring 704 is fixedly connected between the bevel tooth 703 and the supporting plate 702. The bevel tooth 703 is engaged with the partition 701 through the slot 705. A release plate 706 is slidably connected to the inner side of the partition 701, and the side of the release plate 706 conflicts with the oblique side of the bevel tooth 703.

[0051] In order to further facilitate the access to the welding workpiece, the interior of the storage box 601 is divided into two side areas by a partition 701, which is convenient for classifying and storing the welding workpieces. At the same time, if the number of workpieces stored is large, the user can freely adjust the height of the internal carrier plate 702 of the storage box 601 according to the number of workpieces, so as to facilitate the access to the workpieces. The end of the carrier plate 702 is provided with a bevel tooth 703, and the end of the bevel tooth 703 is engaged with the partition 701 through a slot 705 to fix the height of the carrier plate 702. At the same time, due to the inclined structure at the end of the inclined tooth 703, the user can move the carrier plate 702 to the top side through the lifting rod 707. As the number of workpieces decreases, the height of the carrier plate 702 can be raised to facilitate the subsequent removal of the workpieces. When the workpiece needs to be added again, the user can press the release plate 706 located on the inner side of the partition 701. The protrusions on both sides of the release plate 706 will push the inclined tooth 703 to retract. At this time, the carrier plate 702 can be reset to provide maximum capacity for storing workpieces.

[0052] When the present invention is in use, first, when welding the long baffle of the radiator, the placement block 302 and the positioning protrusion 307 provided on the placement block 302 can facilitate the operator to quickly place the workpiece and the long baffle, and the positioning protrusion 307 can effectively prevent the wrong placement of the workpiece. After the preliminary assembly of the workpiece and the long baffle in the placement groove 305 is completed, the clamping cylinder 303 can drive the contact plate 306 to clamp and fix the workpiece in the placement groove 305 to ensure the stability of the workpiece during the welding process. At the same time, the rotating clamping cylinders 304 located at both ends of the tooling bottom plate 301 can press and fix the long baffle on the workpiece, further improving the stability of the workpiece during the welding process, until it passes through the other side of the conveyor table 1. The welding robot 2 completes welding, effectively improving the welding efficiency. After the motor 402 at the end of the conveyor platform 1 is electrically connected to the external power supply, the driving effect of the motor 402 can drive the mounting plate 401 and the tooling on the mounting plate 401 to move as a whole, which is convenient for welding. An inclined guide plate 502 is provided on the bottom side of the placement block 302. When the motor 402 drives the mounting plate 401 and the tooling arranged on the mounting plate 401 to move through the screw rod 403, the tooth block 506 arranged on the bottom side of the mounting plate 401 will be in a meshing state with the side rack 501 on the side of the conveyor platform 1. At the same time, because the mounting plate 401 is in a moving state, the tooth block 506 will oscillate longitudinally under the push of the first spring 507, thereby performing The lifting rod 505 repeatedly pushes the inclined plate 503 at the end of the guide plate 502, and finally makes the guide plate 502 vibrate when the mounting plate 401 moves. In this way, the waste chips generated during the welding process will eventually be discharged into the drop groove 508 on the tooling bottom plate 301, so as to prevent the chips from accumulating on the bottom side of the placement block 302 and affecting the placement of the workpiece. When the metal chips fall into the drop groove 508 of the tooling bottom plate 301, a conveyor belt 803 sleeved on the first roller 802 and the second roller 804 is provided in the mounting plate 401 at the bottom of the drop groove 508. After the welding of the workpiece is completed, when the mounting plate 401 returns to its initial position, the third gear 809 located on the bottom side of the mounting plate 401 will contact with the side rack 501. The third gear 809 rotates accordingly, and the transmission effect of the first bevel gear 807 and the second bevel gear 808 drives the second gear 806 to rotate. The first gear 805 fixed at the end of the second roller 804 meshes with the second gear 806, so that the conveyor belt 803 is finally driven to rotate by the rotation of the second roller 804. As the guide plate 502 continues to oscillate, during the process of the mounting plate 401 returning to its position, the debris falls onto the conveyor belt 803 through the guide plate 502, and is transported to the position of the second roller 804 through the conveyor belt 803, and finally falls and is concentrated in the collection box 801 on the bottom side, which is convenient for subsequent centralized cleaning. At the same time, the side of the collection box 801 is fixed by the positioning rod 810.To prevent the collection box 801 from falling out during the movement of the mounting plate 401, a storage box 601 for storing the workpieces to be welded is provided on the side of the conveyor platform 1. A pulley 603 is provided on the bottom side of the storage box 601 for moving the box as a whole. In order to facilitate the transportation and retrieval of the workpieces, a hook rod 605 is provided on the side of the box. When the storage box 601 slides to the side of the conveyor platform 1, the hook rod 605 will automatically engage with the guide rod 604 on the side of the conveyor platform 1 under the action of thrust, so that the storage box 601 can be quickly fixed to any side of the conveyor platform 1 as needed. The storage box 601 is conveniently positioned to facilitate operators to take out the workpieces through the storage box 601. When the storage box 601 needs to be removed for transporting the workpieces, the user only needs to press the pull rod 602 on the side to make the pull rod 602 rotate. At this time, the end of the pull rod 602 will slide in the first slide groove 610 at one end of the traction plate 607 and push the traction plate 607 to one side at the same time. After the traction plate 607 slides between the storage box 601, the end of the traction plate 607 will simultaneously push the two hook rods 605 engaged with the guide rod 604 through the second slide groove 611, so that the hook rods 605 rotate and release. In addition to the engagement state with the guide rod 604, the user can now remove the storage box 601 for easy use. In order to further facilitate the access to the welding workpiece, the interior of the storage box 601 is divided into two side areas by the partition 701, which is convenient for classifying and storing the welding workpieces. At the same time, if the number of workpieces stored is large, the user can freely adjust the height of the carrying plate 702 inside the storage box 601 according to the number of workpieces, so as to facilitate the access to the workpieces. The end of the carrying plate 702 is provided with a bevel tooth 703, and the end of the bevel tooth 703 is connected to the partition 705 through the card slot 705. 01 are engaged with each other to fix the height of the carrier plate 702. At the same time, due to the inclined structure at the end of the inclined tooth 703, the user can move the carrier plate 702 toward the top side through the lifting rod 707. As the number of workpieces decreases, the height of the carrier plate 702 can be raised to facilitate the subsequent removal of workpieces. When it is necessary to add workpieces again, the user can press the release plate 706 located on the inner side of the partition 701. The protrusions on both sides of the release plate 706 will push the inclined teeth 703 to retract. At this time, the carrier plate 702 can be reset to provide the maximum capacity for storing workpieces.
